SIGNAL LAMP.

Specification of Letters Patent.

Patented June 6, 1922.

Application filed February 13, 1922. Serial No. 536.083.

T 0 all whom it may concern.

lie it known that I. Anvix C. Bnaons. a citizen of the l nited States. residing at. Crisfield. in the county of Somerset, in the State of Maryland, have invented a new and useful Signal Lamp. of which the following is a specification.

This invention relates to a combination tail light and signal lamp for motor vehicles. ()ne of the objects of the invention is to provide a lamp which will serve the function of a tail light. and that of a signal lamp either simultaneously. jointly. or severally.

Another object of the invention is to provide means whereby the conventional tail light may be readily converted into a lamp which in addition to its function as a tail light will serve also as a signal lamp.

The above and other objects of the inven tion are attained by the construction illustrated in the accompanying drawings which form a part of this specification.

Figure l .is an elevation 0t my lamp.

Figure 2 is a disassembled view of my lamp.

Figure 3 is a sectional view of a modified construction of my lamp.

Referring tothe drawings. 5 indicates the conventional tail light. This comprises a casing (S. the side of which is provided with an opening 7, a Socket 8, and a bulb i). The face of tliecasing is usually provided with a red colored glass which is retained within the beaded edge. ll) of the casing by means of a spring wire 11. The cord 12 leads to the wiring system oi the motor car.

The remaining structure shown in Figure 2 constitutes a unitary readily re- -movable mechanism which may be easily ating longitudinally into two chambers. The

casing 13 is thus divided into two chambers one of which 24 is open at both ends, the other chamber 25 being open onlyat the face end of the casing.

A socket 26 is inserted in the chamber 25 through an opening in the casing 13. The socket receives the signal bulb 2?. 19 constitutes an opaque stencil plate which is provided with an opening 20 and a signal sten cil 21. 22 is a red colored lens. The plate 19 and lens 22 fit into the beaded edge 15 of the casing 13 and are retained therein by the spring wire 23. The cord 28 leads from the signal lamp socket 26 to the wiring system of the vehicle.

The assembly of the device is obvious. The lens thatis held in the bead -10 of the tail light casing by means of the wire spring 11 is removed. The flange '14 of the casing 13 is then inserted in the head 10 and the wire spring ll is inserted so as to serve to retain the casing 13 in place. When the device is assembled. the tail light is converted into a combination tail and signal lamp. Without interfering with the conventional functions of the tail light, a simple and inexpensive structure is made to serve the additional function of a signal lamp. it will be noted that when assembled. the casing 13 is'positioned in such a manner that the tail light 9 emanates its illumination through the. opening 20 and also illuminates the license tag through the opening 7 in. the conventional manner. When desired the signal lamp 2? is made to illuminate the stop signal. The lamp 27 may be operated in any manner well known in the art such by a manual switch, by a brake operated switch. or the like.

Figure 3 is a modification of the inven tion in which the partition 29 is curred in such a manner as to reflect the light from the signal lamp 27.

I claim:

l. The combination of a tail light casing for motor vehicles said casing having an open face. with a signal casing provided with means for dividing said signal casing into two longitudinal chambers. means in one of said chambers for receiving a signal light. and means for readily attaching and detaching said signal casing to the open face ot'said tail light casing.

2. The combination of a tail light casing having an open face with a signal casing comprising two longitudinal chambers. means in one of said chambers for receiving a signal lamp, an opaque closure at one end of said chamber and, means for attaching llil the signal casing $0 the open face of the saidcasing adapted to coopeiate'with a tail tail light casing. light casing to hoid said casings togetiiei', in 3.
